Mobile crushers can also be called mobile crushing plants, mobile crushers, etc. It is an inevitable product of high-tech crushing technology in the new era, and its main features are that it can be operated mobilely, can walk freely, and is more convenient for transitions, ensuring that the equipment While the production is safe, the work process is more reliable.
This prevents flour from bonding with water molecules thus making it insoluble in water Flour also contains the protein called gliadin and some lipids both of which are insoluble in water Sometimes you might hear that the molecules in flour such as starch are just too big to be dissolved in water which would explain its water insolubility

A white powder is a mixture of sodium chloride and sodium iodide It is dissolved in water in a test tube An excess of aqueous silver nitrate is added to the test tube A precipitate X is observed An excess of concentrated ammonia is then added to the test tube containing X After the test tube has been shaken a precipitate Y is observed
A magnesium ribbon is burnt in oxygen to give a white compound X accompanied by emission of light If the burning ribbon is now placed in an atmosphere of nitrogen it continues to burn and forms a compound Y a Write the chemical formulae of X and Y b Write a balanced chemical equation when X is dissolved in water
We all know that $ce{}$ is blue and it turns to $ce{CuSO4}$ on heating which is white I also learnt about coordination complexes and d d transitions and how transition metal compounds are colored Recently I came to know that $ce{}$ is also a coordination compound and in its structure four water molecules are coordinated with $ce{Cu^2 }$ and
·The answers to the above questions are given below i Y is sodium carbonate ii The nature of the solution formed by dissolving Y in water is alkaline iii Z is carbonic bicarbonate NaHCO3 is a white crystalline compound that is a constituent of baking is used as antacids and in fire extinguishers When sodium bicarbonate is
As a side note many sources claim that melatonin powder can t dissolve in water However this isn t actually true Research has demonstrated that melatonin powder does indeed dissolve in water—up to a point 4 High melatonin solubility in aqueous medium This myth likely stems from the fact that putting too much melatonin powder in water will prevent some of it from dissolving
·magnesium forms a layer of $ce{MgO}$ readily on it s surface when exposed to air thus preventing further reaction when you put $ce{Mg}$ in water which is actually the $ce{Mg}$ with the $ce{MgO}$ crest on it it is essentially inert to water as the oxide crest won t react and or allow access to the interior where pure $ce{Mg}$ lies
It is also known as Soda crystals soda ash washing soda This inorganic compound is water soluble and when dissolved in water it forms carbonic acid and sodium hydroxide In its pure form it is a white powder and odourless It is a strong base and acts as an antacid
It is a constituent of baking powder and is used in some antacids When heated it gives a compound Y which is anhydrous and absorbs water to become a hydrated salt When this salt is kept in open air it loses a water molecule in a process called efflorescence When dissolved in water it forms a strong base and weak acid Z What is the
·The excess magnesium oxide when we mix it in water it becomes magnesium hydroxide sahibha4603 sahibha4603 When mg is burnt in the atmosphere of an element x white powder is obtained When this is dissolved in water it gives a gas y with pungent smell What are x and y See answer Advertisement
